  • Page 4: Introduction

    D2D Backup System. The objective of this guide is to provide: Step by step instructions on how to configure the D2D NAS share to be used as a disk storage target by a NetBackup media server. The example uses the CIFS protocol.
  • Page 5 Data Movers – send data to external disk-like devices (Open Storage Appliances). Clients – are servers/workstations which have the NetBackup client software loaded and will back up over the network to their designated media server. See the Glossary for more terminology.

  • Page 6: The Role Of The Hp D2D Backup System

    It would be normal to have inter-site replication configured for a different subnet. The initial IP address can be set using the utility disk supplied with each D2D Backup System. This setup utility uses UDP protocol and ‘discovers’ all D2D appliances present on its subnet. The alternative is to use the default DHCP setting and allow a DHCP server to provide the networking information.

    Test setup Figure 4 shows a simple test setup for HP D2D Backup Systems configured as a NAS target for Symantec NetBackup. This configuration will be used as an example in this guide.

  • Page 8: For More Information

    Symantec NetBackup is a very feature-rich data protection application. This guide is only intended to cover basic use for filesystem backup using the D2D Backup System with NAS shares and to use the low-bandwidth replication feature to move data ‘offsite’.

  • Page 9: Configure The D2D Cifs Server

    NetBackup media server is not a member of an AD Domain. AD: In this mode the D2D CIFS server becomes a member of an Active Directory Domain. In order to join an AD domain the user needs to provide credentials of a user who has permission to add computers and users to the AD domain.

  • Page 10: To Join A Domain

    Active Directory. NOTE: If there are problems check that the D2D Backup System has an entry in the DNS (Domain Name System) server. Use the command line to check that the D2D hostname resolves to an ip address and vice versa.

  • Page 11: To Create Shares And Grant Access Permission

    IP address. To create shares and grant access permission Now that the D2D is part of a domain and can be managed, it is possible to create shares and grant access permission to them for domain account users or groups.
  • Page 12 Create a share on the D2D Backup System that is going to be used as a backup target, by selecting NAS — Shares from the D2D Web Management Interface and clicking Create. The shares have default names of Share1, Share2 etc. but these can be changed if desired.
  • Page 13 Now that the D2D Backup System is a member of the domain its shares can be managed from any computer on the domain by configuring a customized Microsoft Management Console (MMC) with the Shared Folders snap-in. To do this first open a new MMC window by typing mmc at the command prompt or from the Start Search box.
  • Page 14 Click Add > and in the dialog box choose the computer to be managed and select Shares from the View options. Click Finish and OK to complete the snap-in set up. Configure the D2D CIFS server...
  • Page 15 AD is used to control access to the D2D file shares. Each service must be stopped and restarted for each account change. The logon is changed from the Windows ‘Services’ configuration. (See page 383 of the NetBackup Administrators guide).
  • Page 16 Having set up the shares the Symantec NetBackup administration console can be used to set up the Storage Units, as described in the next chapter. Configure the D2D CIFS server...

  • Page 17: Configuring Disk-Based Storage

    Basic Disk. This is locally-attached disk storage or network-attached disk storage presented as a filesystem to the media server. The directory structure is specified when the storage unit is created. This is the standard configuration for D2D NAS. Basic disk cannot be used in a storage lifecycle policy.
  • Page 18 Maximum concurrent jobs for the storage unit. (This equates to number of tape drives in a real tape library.) However, be careful that the maximum streams the D2D can manage is not exceeded (see Appendix A). It is good practice to group servers together by application. For example, arrange that file and print servers are backed up to the same share if they are likely to contain some degree of duplicate data because this will improve deduplication results.
  • Page 19 (from the D2D Web Management Interface) to ensure it is within sensible limits. Housekeeping should normally not be increasing week on week. See the D2D Best Practices Guide for more information about monitoring housekeeping.

  • Page 20: Backing Up To And Restoring From D2D Nas Shares

    4 Backing up to and restoring from D2D NAS shares Creating a backup policy This section will describe how to create a backup policy using the storage unit created in the previous section. NetBackup 7 provides a ‘wizard’ for policy creation.
  • Page 21 The next step is to specify the files for backup. Select Add, click on the small folder icon and select the desired directory path. Click Next> to display the Backup Type screen. This screen is used to specify Full Backup or Incremental Backup.
  • Page 22 As an example it would be desirable to keep the full weekly backups for a month and the full monthly backups for 6 months. Incremental may only be retained 2 weeks. Click Next> and specify the start time. Backing up to and restoring from D2D NAS shares...
  • Page 23 The policy is now fully configured and the next screen completes the process. 10. The created policy should now be displayed in the main NetBackup Administration Console under the Policies section. Click on the actual policy and it is possible to show some additional attributes.

  • Page 24: To Run The Backup Policy

    This is useful in checking that the correct services are running. You may see that Device Manager service is not running. This is correct if no tape library is configured.) Backing up to and restoring from D2D NAS shares...

  • Page 25: Catalog Backup

    The next screen is very important and is used to specify the location of the catalog disaster recovery file that is vital for catalog recovery. This file can be stored on the D2D or another disk media attached to the media server but it needs to be stored offsite along with the catalog backup.

  • Page 26: D2D Nas Open File Limits Best Practice

    Each D2D Model has different limits for the number of open files it can support – see Appendix A. Event logging on the D2D will inform the user if any of these limits have been exceeded, so it is a best practice to regularly check the Event logs because backups may pause when the number of open file limits is exceeded.
  • Page 27 Select a backup policy from the list to display the relevant directory tree. This information is obtained from the catalog. Tick the box of the required file and use the Actions menu to initiate the restore. View status will show progress, as illustrated below. It is also possible to restore files to different locations and other servers.

  • Page 28: Recovering From A Disaster Situation

    In the test example used to illustrate this guide the NAS shares are set up to replicate between D2D Backup Systems. In a real life scenario the units would be located on different sites and connected via a WAN link. It is also quite likely that the master server would stay at a central location with several D2D Backup Systems connected to remote media servers, using replication to move data from the remote offices.

  • Page 29: If The Master Server Is Lost

    It is now assumed that the remote office is lost and so is the primary data on the D2D Backup System. However the copies of the share are intact on the target D2D Backup System.
  • Page 30 Run the Catalog Recovery Wizard from the NetBackup Administration console. Enter the full pathname to the disaster recovery file. If the file is located on a D2D share it can be mapped to a drive letter and then the browse button can be used to locate it.
  • Page 31 The next screen will restore the catalog. (There is an option not to recover the relational database.) Click Next. The catalog recovery will proceed and advise of success. Click next and On successful completion of catalog recovery the NetBackup server should be restarted and then the restore client can be used (as we did previously in the restore section) to recover files as required.

  • Page 32: A Open File Limits And Recommended Streams Per Nas Share For D2D Backup Systems

    The HP D2D NAS target for backup does not deduplicate the first 24 MB of any file for performance reasons. Some backup applications generate control files during backup to NAS that are constantly changing – to try and deduplicate constantly changing files slows down the deduplication process.
